/search/artists, /search/albums, /search/tracks each read ?q= and run their own createSearchInfiniteQuery (limit=50). Load more pulls the next offset; back link returns to /search?q=. Empty q shows a 'no query' prompt and fires no request. Tracks overflow uses the onPlay prop on TrackRow to call playRadio(track.id).
